             Permanent Magnetic Lifters(PML)|permanent  lifting magnets, adopting steel or iron is an ideal and convenient lifting  equipment with pressurizing structure which is hard and powerful to load, unload and move heavy objects such as ferrous materials and work pieces. Permanent Magnetic Lifters include various types and levels such as manual magnetic lifter and automatic magnetic lifter and are widely applied as hoist devices in industries and many other fields. One of the most prominent feature of permanent magnetic lifters is that no electricity is needed to operate the magnetic lifter, once operated there is less than 1% residual magnetism.

           The permanent magnetic lifters' highest pulling force is 3.5 times greater than rated lifting capability. With the installation of the simple switch and safety bottom design, it allows for one handed operation. Before operation it is necessary to find out the  percentage of the steel thickness of the component and capacity curve. And if the components surface roughness is less than 6.3um, the magnetic lifter surface  gap will not exist, the lifter gap should be estimated. Then the need for slings, clamps and special lifting frames can be eliminated with the use of a magnetic lifter.

           These two pole permanent magnetic lifters with two poles at the bottom of the lifter, using high grade magnets for producing strong magnetic flux path through the two poles. The lifter is placed on the MS or block that is to be lifted. With the  turn for the handle on its on position, it ensures the completion for magnetic flux path through the MS body, which gets attached to the lifter. Made of two parts such as permanent sucker and discharge device, the magnetic force wire generated by the permanent magnet will go through the magnet-conductive plate and attract materials forming a closed circuit thus to achieve lifting steel materials.

2. Manual HandleHand leverHand shakeHandle bar
         The handle on the magnet features a lock-on/lock-off mechanism that requires the operator to manually switch between the two states (On and off) without extra power. The handle controls an inner magnetic system for safe and easy operation. When the handle is placed at the OFF position, the lifting magnet would have almost no magnetic pull. After you press the safety release button on the top of the handle and turn it to the ON position, the lifting magnet would then have magnetic attraction pull to a steel load. For better safety insurance, the handle is secured at this position by a lock pin. The lifting magnet would preserve full magnetic pull until you manually slide back the lock pin and turn the handle back to the OFF position. The magnets are activated / deactivated easily by turning a locking lever. In activated condition the hand lever will  be safely locked and thus prevent unintended demagnetizing. This prevents the handle from being turned only ”partially on” and giving the operator a false sense of security that the magnet is holding safely, or from being accidentally bumped to the “off” position, dropping the load pre-maturely you can use very light force to roll the handle for opening so that you work will be more efficient.

3. Two polesTwo posts
           These are at the base and produce strong magnetic flux path with high quality Magnets through the bottom poles. Turning so as to lift and discharging of materials is accomplished the handle to on and off positions. These are utilized widely for dependable lifting, stacking, or emptying of MS squares, adjust, or squePermanent Magnetic Lifter molds. It uses front line neodymium magnetic framework for consistent execution. The magnetic lifter is placed on the MS flat/block that is to be lifted.
4. “V” type grooveV-shape slot
         The ‘V’ slots are incorporated into the holding face allowing it to be used to lift pipes or round bar work pieces. When lifting and handling cylindrical components, keeping the cylindrical surface contacts the “V” slot of lifter on two lines. The mirror surface is treated with high-end nameplate and adopts the an-it collision hand shank design.

5. Ring
           Installed on the top of the lifter, the forging slip rings are lighter, more secure and are not easy to deformation and fracture. Besides, the ring wayward high and easy to wear.
6. U-loop shackle hook
         They are fixed on the top of magnetic component firmly, allowing for the easy attachment of  slings and low residual magnetism for rapid handling. There is a rated shackle stamped with the Working Load Limit (W.L.L.); Test No.; Serial No.; Forged hook for high mechanical strength and durability. They have a lot of good qualities such as nickel plated, rust-proof, flashing and quite strong.

7. Magnet chuck
           Make sure the center of magnet chuck and work weight coincides.
8. Crank
           Before lifting, turn the crank from  “-” to “+” to check if it’s auto-locked, then crane.
           After finish lifting, turn the  crank from “+” to “-”. Then the work piece will drop off.
9. B chamfer liner
          When lifting round work-piece, keep B chamfer liner contact with the work piece adjacent angel. So the lifting force will be only 30%~50% lifting capacity.

16. Bolts

High Quality Permannet Magnetic Lifter China Supplier1-13.jpg

           1. Conform to Chinese top standard (it EN 13155 TUV approved) (idt AS4991
           2. Ambient air temperature no higher than 80℃. 
           3. Test certificate for safety factor from government approved third party
           4.Factors that can decrease the magnet’s lifting ability
           Load Surface Conditions: Any rough  surface caused by air, dirt, paper, rust, paint and scale act will between the  magnet and the load will hinder the magnetic lines of force flow from flowing easily. Find out the percentage that lifting capacity of the permanent magnetic lifters may reach from the air gap-lifting capacity curve shown in the performance chart. Combine these two factors and calculating the lifting capacity that the lifter may reach.
           Load Length and Width: The increase of length or width of the load will make it not flat, and then the dropping will create an air gap to limit the flow of magnetic forces
           Load Thickness: The thinner the load is, the less iron is applied, and then fewer lines of  magnetic force flow. But thin magnetic-inductive material can also be lifted as  long as their thickness is more than 5mm
           Load Alloy: Influenced by the composition of steel component. Alloy which contains nonmagnetic materials such  as ANSI304 is a poor conductor. So, we’d better choose those low carbon steels such as soft iron or mild steel.
           5. Operation  
           Attach the permanent magnet lifter to suitably tested lifting equipment with the body hook. Then determine the load weight in the center of gravity. Once in position, move the magnet level fully anticlockwise until it is held captive by the level lock. After attached, rise and move the item to where it is required. Before lifting/moving, ensure the load is free, and lift the load a nominal distance to check balance and  security of the load. Finally, use tag lines to control long or bulky load.

           6. Caution

           Keep surface fully clean
           Wooden or non-magnetic surface won’t work
           Make sure that the security moved flexibly and the security pin locked firmly.
           Ferrous and casting is  acceptable on the condition of enough flat area.
           People are not allowed to stand under the steel sheet.
           Keep off after finished.
           Move smoothly without vibration Overload is banned
           The temperature of work piece and ambient cannot over 80degree
           Never move the handle to “ON” side, except on an iron object of holding

           7. Maintenance

           Paint oil/grease
           Put it on thick wooden plank
           8. The Little Permanent Magnetic Lifter weighing only 5.5 lbs. and safely lifts 220  lbs...With a 3.5X safety factor that’s 770lbs
           The Big  Permanent Magnetic Lifter lifts up to 6,600 lbs. With a 3.5X safety  factor, 23,100 lbs.
           Calculate that the magnet will safely lift your material.  
           9. The Maximum Load (ML) is different for plate and round materials and also depends upon stock thickness carbon content and surface finished
           Calculating Maximum Loads
           Maximum lifting power is differs for plate and round materials, carbon content, thickness & surface finish.
           Calculation Example: ELM-600, rated lifting power is 1,320 lbs.
           The formula for calculating range of lifting capacity is: T x F x M x  CapacityELM-600 Example: T8, F1, and M2, 90% x 125% x 85% x 1,320 = 1,263  lbs.

           10. Electro Permanent Magnet System VS Electromagnet System
           AS regard to the source of the magnetic force, Electro Permanent Magnet System is controlled by NdFeB or  AlNiCo, while Electromagnet System is produced by electrical current flow. Besides, Electro Permanent Magnet System have two kings of magnetization and control the work load at the pole face while Electromagnet System just can control the work load only. Another difference is about demagnetization, Electro Permanent Magnet System doesn’t need to isolate but Electromagnet have to. And Electro Permanent Magnet System is free of electricity and more reliable than Electromagnet System. In terms of the maintenance and operational cost, Electro Permanent Magnet System is more economical because it consumes no electricity during operation and has long lifespan. When they have to lift 15tons objects, Electro Permanent Magnet System are more light weight than Electromagnet System. With simplified than electromagnetic separator without power supply and coolong system
         11. The max pull-out force can reach 3.5 times of rated lifting capacity with high safety factor
